“…A higher calcination temperature enhances the green emission intensity suggesting a correlation between green emission and isolated oxygen vacancies as proposed by others [40]. With increasing calcination temperature; the kinetic energy of atoms in ZnO lattice will increase and the escape rate of oxygen atoms from ZnO lattice will be faster than rate of getting oxygen atoms to lattice [41] resulting in more vacancy formation and higher green emission.…”

“…In the visible emission spectrum, different defects are attributed to the green, yellow, and orange-red emissions [16,27]. The green emission band is attributed to a variety of defects including singly ionised oxygen vacancies [28][29][30][31], antisite oxygen [17,32,33], zinc interstitials [34], and zinc vacancies [35]. Given that there is no consensus in the mechanism for green emission, this shows how highly debated the origins of the luminescence are for ZnO [36,37].…”

Room-temperature single-photon emission from zinc oxide nanoparticle defects and their in vitro photostable intrinsic fluorescence

Zinc oxide (ZnO) is a promising semiconductor that is suitable for bioimaging applications due to its intrinsic defect fluorescence. However, ZnO generally suffers from poor photostability. We report room-temperature single-photon emission from optical defects found in ZnO nanoparticles (NPs) formed by ion implantation followed by thermal oxidation in a silica substrate. We conduct a thorough investigation into the photophysics of a particularly bright defect and identify other single emitters within the NPs. Photostability was observed when the NPs were removed from the growth substrate and taken up by skin cells for in vitro imaging.

“…These Mo related Raman peaks shift a few wavenumbers to lower energy compared with results from other literatures. There are two possible reasons, one of which is that the quantum confinement effect leads to the broken of symmetry in NPs and therefore the originally prohibited transitions are allowed, bringing in some new peaks [28]. Tensile strain at the core/shell interface is another reason for the shifts.…”
